After

• Cable Receive Interference Rejection Test

– Test Equipment: MQP USB-PDT

– The related CTS spec. will be confirmed after getting E-Marker IC certified

PD Only Silicon Issues On Compliance Testing

PD Only Silicon Issue (#1)

• TD.PD.VNDI.E8 Accepts PR_Swap as Sink

– Test Equipment: Ellisys EX-350

– This test verifies that the UUT will accept PR_SWAP as sink as indicated in the vendor-supplied information.

– Vendor Info File:

– Trace File

15

PD Only Silicon Issue (#2)

• Source Dynamic Load Test, Consumer/Provider Accepting Swap

• Google PD analyzer (Sniffer Function) : capture CC Pins Communication log

• Wilder Type-C PD coupon (Power Measurement) : measure Vbus Voltage & Current

Combination Solution Modularized Solution

Allion Type-C Digital Power Meter

Plug to Receptacle

The real-time voltage/ current with csv Log ▪Voltage : Can be monitored on 5V/9V/12V/15V/20V as Max. (Optional Voltage and current can also be monitored) ▪ Current: The “+” / “-” mean the Current charge (Plug→Receptacle or Receptacle→Plug)

Case Study

Condition: two devices are connected with each other Observation: in case of the role function confusion , the role can be changed by UI implement

Case A: Power Role / Data Role Swap Functionality

37

The USB Connection Mode An Example of LG Google Nexus 5X and HUAWEI Google Nexus 6P connection:

With the role swap capability, the UI “USB connection mode” on mobile phone is convenient for customer to identify the role function as they wanted.

Power Role : to charge or to be changed Data Role : host or device

Case B. Inconsistent Results of USB Charging Compatibility Test
